I had PND after DD2 was born. I didn't get help because I was breastfeeding and I didn't want to be put on anti-depressants.
I was so used to being in control and coping and being ok and everything had been so easy with DD1 that it came as a real shock. I have never been in such a dark place in my life and the worst thing is once you've been there you never forget it, a little corner of your mind is always in shadow. Thank god I came out of it before I did any damage to myself or my DDs.
Makingdo - I'm sure you are making up for lost time now.
Good luck with the next baby.
